Description

Technical Field

[0001] The present application relates to the technical field of deep hole drilling machines, and more specifically, to a bracket flipping mechanism of a deep hole drilling machine. Background Art

[0002] A deep hole drilling machine is a special machine tool used for processing deep holes. It can accurately drill holes with a depth relatively large relative to the diameter. A deep hole drilling machine usually includes a spindle seat, a sliding seat, a spindle, a feed drive mechanism, a rotary drive mechanism, a drill bit and a bracket. Two sets of slide rails parallel to the length direction of the spindle seat are provided on the front side of the spindle seat. The sliding seat is slidably connected to one set of slide rails. The spindle rotates with a sliding seat parallel to the slide rails. One end of the drill bit is connected to the spindle. The rotary drive mechanism is installed on the sliding seat to drive the spindle to rotate and drive the drill bit to rotate to drill the workpiece. The feed drive mechanism is installed on the spindle seat and connected to the sliding seat to drive the sliding seat to slide back and forth along the length direction of the slide rail to realize drill feed. The bracket is slidably connected to another set of slide rails to support the drill bit at various positions, ensuring the stability and precise positioning of the drill bit during the drilling process.

[0003] In the related art, the slide rail slidably connected to the bracket is usually spliced ​​in two sections, one section of the slide rail is fixedly connected to the spindle seat, and one end of the other section of the slide rail is installed on the mounting plate. The bottom end of the mounting plate is hinged to the spindle seat, and the top of the mounting plate is fixed to the spindle seat by bolts. When the bracket needs to avoid the drill bit from feeding, the bracket is slid into the section of the slide rail hinged to the spindle seat and then the bolt is twisted to make the mounting plate on which the section of the slide rail is installed flip downward to achieve the bracket avoiding the drill bit feeding. This method requires manual tightening of the bolts, and manual support and manual flipping of the slide rail, which makes the bracket less efficient in avoiding the drill bit, resulting in low processing efficiency and a large workload for workers. Utility Model Content

[0006] Preferably, the driving assembly includes a cylinder and a swing arm, the cylinder is vertically fixed on the back side of the spindle seat, the telescopic axis of the cylinder faces the bottom side of the spindle seat, one end of the swing arm is fixedly connected to the rotating shaft, and a hinge joint is provided at the end of the telescopic axis of the cylinder, and the hinge joint is hinged to the end of the swing arm away from the rotating shaft.

[0007] Preferably, the mounting frame includes two mounting blocks, both of which are fixed to the bottom side of the spindle seat and arranged at intervals along the length direction of the spindle seat. Both of the mounting blocks have openings running through them on their sides, and the rotating shaft is passed through the two openings. Ball bearings are provided between the hole walls of the two openings and the outer wall of the rotating shaft to support the rotation of the rotating shaft.

[0008] Preferably, the flip seat includes a mounting plate and a connecting sleeve arranged on one side of the mounting plate, the rotating shaft passes through the connecting sleeve and is connected and fixed to the rotating shaft, the second slide rail is fixed to a side of the mounting plate away from the connecting sleeve, the mounting plate extends into the avoidance groove, and the thickness of the mounting plate matches the recessed depth of the wall avoidance groove.

[0009] The present application includes beneficial technical effects as follows: by moving the bracket onto the second slide rail, the driving component drives the rotating shaft to rotate, and the rotation of the rotating shaft drives the flip seat to flip toward the bottom side of the spindle seat, so that the second slide rail drives the bracket to flip toward the bottom side of the spindle seat, so that the bracket avoids the drill bit feed, and the driving component drives the rotating shaft to rotate instead of manually tightening the bolt operation, with a high degree of automation, reducing manual operations, reducing the workload of workers and having high efficiency, which is convenient for improving the processing efficiency of workpiece drilling.

[0013] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0014] Reference Figure 1 and Figure 2The two cams 32 are connected to each other by a screw thread, and the two cams 33 are connected to each other by a screw thread, and the two cams 33 are connected to each other by a screw thread, and the two cams 33 are connected to each other by a screw thread. When the support 6 is moved to the first slide rail 5, the turning seat 4 drives the first slide rail 5 to turn toward the bottom side of the spindle seat 1 to achieve the support 6 turning to the bottom side of the spindle seat 1 to avoid the drill bit.

[0015] Reference Figure 1 and Figure 2 The drive assembly 7 includes a cylinder 71, a swing arm 72 and a connecting piece 73. The connecting piece 73 is fixed to the top side of the spindle seat 1 and extends toward the back side of the spindle seat 1. The bottom end of the cylinder 71 is fixedly connected to the connecting piece 73. The cylinder 71 is supported by the connecting piece 73 and is placed vertically. The telescopic axis of the cylinder 71 faces downward. One end of the swing arm 72 is fixedly connected to the rotating shaft 33. The end of the telescopic axis of the cylinder 71 is provided with a hinge joint 74. The hinge joint 74 is connected to the end of the swing arm 72 away from the rotating shaft 33. The swing arm 72 is driven to swing by the cylinder 71, and the swing arm 72 drives the rotating shaft 33 to rotate. The telescopic shaft of the cylinder 71 retracts and pulls up one end of the swing arm 72, so that the swing arm 72 drives the rotating shaft 33 to rotate clockwise, causing the flip seat 4 to flip toward the bottom side of the spindle seat 1. The telescopic shaft of the cylinder 71 extends and pushes down one end of the swing arm 72, so that the swing arm 72 drives the rotating shaft 33 to rotate counterclockwise, causing the flip seat 4 to flip toward the top side of the spindle seat 1, so that the flip seat 4 flips to the avoidance groove 11, so that the first slide rail 2 and the first slide rail 5 are docked.

[0016] Reference Figure 1and Figure 2 The flip seat 4 includes a mounting plate body 41 and a connecting sleeve 42 arranged on one side of the mounting plate body 41. During installation, the connecting sleeve 42 is placed between the two mounting blocks 31. When the rotating shaft 33 passes through the opening 32, it also passes through the inner hole of the connecting sleeve 42. The inner hole diameter of the connecting sleeve 42 is adapted to the diameter of the rotating shaft 33. The rotating shaft 33 passes through the inner hole of the connecting sleeve 42 and performs interference fit with the connecting sleeve 42 to achieve fixation with the connecting sleeve 42. The first slide rail 5 is fixed to a side of the mounting plate away from the connecting sleeve 42. The mounting plate body 41 extends into the avoidance material. The thickness of the mounting plate body 41 matches the recessed depth of the avoidance groove 11 so that the first slide rail 2 and the first slide rail 5 are flush in the horizontal direction.

[0017] The implementation principle of the bracket flipping mechanism of the deep hole drilling machine tool in the present application is: the various positions of the drill bit are supported by sliding the bracket 6 on the long slide rail, and the bracket 6 slides to the second slide rail. The telescopic rod of the cylinder 71 pulls up one end of the swing arm 72 to swing the swing arm 72 and drive the rotating shaft 33 to rotate clockwise. The rotating shaft 33 rotates clockwise to drive the flip seat 4 to flip toward the bottom side of the spindle seat 1, so that the first slide rail 5 drives the bracket 6 to flip toward the bottom side of the spindle seat 1, so that the bracket 6 avoids the drill bit feed. Compared with the manual support and torque bolt method to flip the bracket 6, the flipping efficiency of the bracket 6 is higher when driven by the cylinder 71, which is beneficial to improving the processing efficiency of the workpiece and reducing the workload of workers.
